-------------Mike,
I just know that John (barythrin) won't think of it, but any guidance you could provide as to how to use the ROM expander would be greatly appreciated.

A bit of a misnomer I suppose; not really an 'expander' but a 'selector'. The problem was that there were all sorts of accessory ROMs (I've got a half dozen); some were actual software or components of software (like the Command-O ROM we're talking about here) and some were just copy-protection 'dongles'. Since there were only two sockets available (and most went into the 9000 socket anyway) you'd have to swap ROMs when you went from using WordPro to programming with Command-O (for example), so just like the C64 and VIC20 cartridge expanders presently being discussed on another thread you had these (EP)ROM expanders for the 24-pin PETs. Most of them (like the Quadra ROM pictured) would have a DIP or rotary switch to select the desired ROM; if you didn't feel like going 'under the hood' then you'd run a little cable to a switch somewhere on the side or back (but no serious user ever screwed down the top anyway). AFAIK there were no software-selectable versions; at least I never saw any...
